Abstract (en)

[origin: US2022372908A1] A method for operating an internal combustion engine, which comprises a combustion engine, a fresh gas line into which a fresh gas compressor is integrated, wherein the fresh gas compressor can be driven by an electric motor, and an exhaust gas line, in which an exhaust turbine, which has a variable turbine geometry, a bypass line with a bypass valve for bypassing the exhaust turbine as required, and, downstream of the exhaust turbine and the bypass line, an exhaust gas aftertreatment component are integrated, wherein if, during operation of the combustion engine, an operating temperature of the exhaust gas aftertreatment component is below a set temperature, the bypass line is at least temporarily released, the fresh gas compressor is driven by the electric motor, and the VTG is set to a closed position of at least 50% or at least 80% or at least 90% or 100%.
